Homeopathic solutions induce production of winged forms in aphid

The aphids control (Brevicoryne brassicae L.) in kale (Brassica oleracea L. var. acephala) is one of the main challenges for its production. This obstacle becomes greater agroecological production systems. Thus, objective this study was to verify formation winged individuals colonies B. aphids, when exposed treated with homeopathic solutions. treatments were resistant 5CH, susceptible attacked aphid nosode 30CH, and controls that are water (without dynamization) distilled + 70% ethanol being applied every day 15 days. Kale plants inoculated irrigated using After days inoculation, removed from bag number forms nymphs counted. Homeopathic preparation Resistant 5CH provided a smaller larger per colony. homeopathy showed higher but reduced nymphs. Aphid 30CH treatment promising Brevicoryne plants, as it induced polymorphism, presenting
